PLOW.

Specification ofLetters Patent.

Patented Oct. 8, 1907.

Application filed August 15.1906. Serial No- 330,759.

To all whom it may concern:

Be it known that I, EbMoND J. INGRAM, a citizen of the United States, residing at Scott, in the county of Lonoke and State ofArkansas, have invented new and useful Improvements in Plows, of which the following is a specification.

This invention relates to plows of the rotary disk type and has for its objects to produce a comparatively simple, inexpensive device of this character which will, in practice, efficiently perform its functions, one wherein the plow beam may be readily adjusted toward and from the ground for setting the disks at the proper angle relative to and controlling their depth of entrance into the soil, one wherein the soil will-be effectually broken in rear of and on a line centrally between the disks, and one in which the operation of adjusting the plow beam vertically may be conveniently performed from the drivers seat.

With these and other objects in view, the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanying drawings: Figure 1 is a top plan view of a disk plow embodying the invention. Fig. 2 is a side elevation of the same, partly in vertical section, the section being taken on the line 22 of Fig. 1. Fig. 3 is a view, partly in vertical, transverse section, the section being taken on the line 33 of Fig. 1.

Referring to the drawings, it will be seen that the plow frame comprises a main, central, longitudinal beam 1, a cross beam 2, a front axle 3 equipped with transporting wheels 4, and a rear axle 5 equipped with transporting wheels 6, there being bolted to the front axle 3 a vertical arch member 7, through which and the axle there is extended a vertical bolt 8 provided at its upper end with a f orked or bifurcated head 9, while arranged for vertical sliding movement on the bolt 8 is a bearing head 10 to which the forward end of the beam 1 is attached. The rear axle 5, which is provided with a substantially U-shaped crank portion or bend 11 is journaled in bearings 12 beneath the beam 1, and has pivotally mounted on the rear end of said crank portion a vertical arch member 13 connected by a link 14 with the lower end of an operating lever 15 arranged within convenient reach from the drivers seat 16 and having as usuala locking pawl 17 adapted for engagement with the teeth of a segmental rack 18 to fix the lever against movement, it being apparent that by manipulation of the lever the axle 5 may be swung ,upward or downward, thus to adjust the rear end of the beam toward and from the ground, as more fully hereinafter explained, while pivoted between its ends in the forked head 9 of the bolt 8 is a second operating lever 19 having its rear end disposed within reach from the seat 16 and its forward end connected by a link 20 with the bearing member 10, the lever 19, which may be manipulated for raising or lowering the forward end of beam 1, being equipped with a pawl 21 adapted for engagement with the teeth of a rack 22 to hold the lever against movement and thus fix the beam in adjusted position.

Fixed on the ends of the cross beam 2 are spindles 23 on which are journaled for rotation rotary disk-like plow blades 24 set on lines which diverge from front to rear, the blades, which are of concavo-convex form and disposed with their concaved faces outward, being pitched on lines which incline downwardly and outwardly from the vertical, while bolted or otherwise attached to an upturned bearing portion 25 at the rear end of the beam 1 is a downwardly and forwardly inclined standard 26 carrying at its lower end a colter blade 27 adapted to break the soil on a central line between the blades 24, the standard 26 being slotted as at 28 for the reception of the attaching bolts 29, thus adapting the standard for an initial vertical adjustment in adjusting the colter 27.

Attached to the front axle 3 is a forwardly extending draft yoke 30 having at its forward end an eye 31 with which the draft bar may be attached in hitching the draft animals to the plow.

In practice, the levers 15 and 19 may be manipuends of the beam 1 relative to the ground, as heretofore explained, thus to control the depth of entrance of the plow disks 24 into the soil, it being evident that in the operation of adjusting the beam any desired fore and aft inclination may be imparted thereto for effecting a corresponding pitch of the blades 24. As the machine advances over the ground, the disks 24 will operate with a rotary shearing cut for turning the soil outward from the machine and at opposite sides thereof, while the blade 27 will break the unplowed strip of ground which lies between and is not acted upon by the disks 24. It will be observed that the standard 26 may be quickly adjusted for varying the depth of entrance of the colter 27 into the ground, and further that in the operation of adjusting the forward end of beam 1 the bearing block 10 will be properly guided in its movements upon the bolt 8.

Having described my invention, what I claim is:

1. A plow comprising a central beam, :1 front axle, a vertical bolt, means on the front end of the beam pivotally connected with the bolt and slidable on the latter and adapted to rest directly on the axle when in lower most position, means for raising the front end of the beam, a rear axle having a central (I-shaped crank portion disposed directly under the beam and adapted to straddle the same, a link connected with the rear axle, an operating lever fulcrumed on the beam, an arm movable with the lever and connected with the link, a toothed sector carried by the beam, and a latch device on the lever arranged to engage the sector.

2. A plow comprising a central beam, at front axle, an arched member thereon, a vertically extending bolt passing through the axle and member, a connection between lated for adjusting respectively the rear and forward the front end of the beam and bolt for permitting the vbeam to hinge and move vertically on the bolt, wheels on tween the rear portion of the beam and rear axle for rals-- ing and lowering the beam.

3. A plow comprising a central beam, oppositely disposed rotary disks attached to the beam, 21 rear axle having a central U-shaped crank disposed under and journaled on the beam and capable of straddling the latter from underneath, wheels on the ends of the axle, airinverted Ushaped member spanning the beam and hingedly connected with the axle, a lever fulcrumed on the beam and connected with the member for raising and lowering' the beam with respect to the wheels, and a stationary blade depending, from the beam and arranged in a plane extending between the rotary disks.

In testimony whereof, I aflix my signature in presence of two witnesses.
